HEATER.'

Specification of Letters Patent. I Patented Beg, 19, 1916,

Application filed March 31, 1916. SerialrNo. 88,031.

To all 'whom t may concern:

'Be it known that I, JOSEPH R. TOURONGEAU, a citizen of the United States, residing at Mai-tinten, in the `county of Iroquois and State of Illinois, have invented new and useful Improvements in Heaters, of which the following is a specification.

This invention relates to heaters 'for automobiles and other motor-driven vehicles in which the heating medium is the exhaust of the engine.

The invention has forits object to provide a heater .of this 'kind which is simple and eihcient, and which is so constructed and connected up that it may be readily installed without making any alterations in the strucl ture of the car.

A further object of the invention is to provide a heater which may also be employed as a muliier cut-out.

The invention also has for its object to provide a heater which operates without noise. l

Other objects and advantages of the invention will be pointed out in the detailed description appearingv hereinafter, and in order that the same may be better understood, reference is had to the accompanying drawing, 1in which- Figure 1 is a perspective view showing the application ofthe invention, and Fig. 2

is a sectional View thereof.

Referring specifically to the drawing, the

heater is composed of a tube 10 of suitable length so that it may extend across the' floor of the carl from one side to the other, the

length of the tube therefore depending on the width of the car body. One'end of the tube is closed, and the other end is open tp the atmosphere, said open end having an elbow -11 which extends downward when the tube is mounted iu place.

Mounted lengthwise in the tube 10, in spaced relation therewith, is an exhaust conducting pipe 12 having side outlet perforations 13. .This pipe is suitably fixed in the tube and 'extends .throughout substantially the entire length thereof. To that end of the pipe which is at the elbow 11, is connected a flexible tube 14 which delivers into the pipe the exhaust from the engine, the latter being indicated at 15 and its exhaust pipe at 16, the ltube 14 being connected to the exhaust pipe in a manner to be presently described. y

Two heating units are shown, one for the of the heating units.

occupants of the front seat of the car, and one for the rear seat. It will, of course, be understood that this arrangement may be varied, and the invention is not limited to any particular number .of heating units.

To, the exhaust pipe 16 of the engine l'is Y connected the usual muffler 17. The exhaust part coupling sleeve 19 having a lateral branch 20 terminating in two branches 21 to which the tubes 14 are connected. In the branch 20 is a valve or damper 22 actuated by a lever 23 and a wire 24 extending to the front seat so as to be within easy reach of the driver.

When the `valve 22 is open, a portion of the exhaust passesthrough the tubes 14 into the pipes 12 from which it escapes through the perforations 13 intothe heater tubes 10, vthe latter being thus heated. The exhaustescapes to the atmosphere from the tubes 10 through the open ends thereof. The tubes 10 also operate as mullers, and the heaters are therefore absolutely noiseless-in operation.

The' heater tubes l0 are mounted on the floor of the car in front of the seats, yso as to be within easy reach of the feet of the occupants of the car. On one sideof the car, the Hoor is .cut away at the end as indicated at 25, to accommodate the bends 11, the latforations 13 distribute the hot'gases thrbuglyxout the entire length of the tubes, and the lutter are thus uniformly heated. l

The heating units can be readily removed upon disconnecting the tubes 14 frodi the coupling branches 21, and when this is done, the valve 22 will be kept closed so that there will be no escape of the exhaust, exceptby the way of the muffler 17.v The valve may also be openedV to serve as a mufller cutout, the exhaust thus escaping from the branches 21.

' I claimt- 1. A heater for motor vehicles utilizing the exhaust of the engine comprising an elongated tube closed at one end and having at the other'end a laterally directed elbow whieh opens to the atmosphere, a pipe mounted lengthwise of the'tube in spaced relation therewith and having outlet pertorations thereinto, and an exhaust conducting' tube connecting the pipe With the engine exhaust, said tube entering the irst'mentioneil tube through the elbow in spaced relation with the interior thereof.

2. 4A yheater for motor vehicles utilizing the exhaust oi' the engine, comprising an elongated tube closed at one end and havingr at the other end a laterallyA directed elbow which opens to the atmosphere, a pipe mounted lengthwise ot' the tube in spaced relation therewith and having' outlet perforations thereinto, an exhaust conducting tube detaehabl)y connected at one end to the exhaust pipe ot the engine, and at the other end to the aforesaid pipe, said exhaust conducting` tube enteringT the first mentioned tube through the elbow and in spaced relation with the. interior thereof.

In testimony whereof I aliX my signature.7
